1. Uses and importance of Titanium (Ti) Name: Lai Tsoi Yin (6) Ng Tsz Lam (14) Siu Long Ying (18) Tam Ka Yee (19) Class: S.5D

2. Introduction -Properties of titanium:  Low density  Hard  Relatively high melting pt.  Silver color  Low electrical and thermal conductivity  Non-magnetic  Excellent resistance to corrosion

3. Uses  Usually alloyed with Al, Cu, Mg and V  Industrial - welded titanium pipe → corrosion resistance  Pigments, additives and coatings (titanium dioxide) - give a pure and brilliant white color

4.  Jewellery - durability, light, easily coloured, corrosion resistance  Aerospace and marine - high strength & resistance → making aircrafts, naval ships  Medical - stabilizing the fractured bones - biocompatible

5. Importance  Catalyst  Excellent corrosion resistance - passive oxide surface film  Usefulness: its alloys  Useful: medical, jewelry, architectural, industrial, aerospace, marine  Stimulate the production of carbohydrates & encourage growth in plants
